nvme-apple: Reset q->sq_tail during queue init
Fixes a "duplicate tag error for tag 0" firmware crash during controller
reset while setting up a queue on Apple A11 / T8015 caused by stale
entries in the submission queue due to an invalid sq_tail offset after
reset.
Fixes: 04d8ecf37b5e ("nvme: apple: Add Apple A11 support")
